I have 5 kids (so essentially the same scenario) except the dogs take a bit more space. Suburban is the answer. Used vehicles are sky high pricing right now. Do a private party Tesla sell for a much better than dealer price and order a new suburban (used is more expensive than new right now). It will be about the same quality as your tesla, and cost much more to drive, but it really is the best (cost within reason) option. My wife became the queen of backing into parking spots in the big vehicle.
